Product Description

Bellow Pressure Reducing Valve  
MODEL: Y44H, Y44T
   



Y44H Bellows Pressure Reducing Valve Use Description
This product is used for the temperature bellow 200ºC medium steam, air, water, non-corrosive medium in the pipeline. This valve functions to maintain a constant pressure to user's request. Inlet pressure P1 range 1.0-0.1MPa; Outlet pressure P2 range 0.4-0.05MPa. The pressure difference before the valve and after the valve should less than 0.6MPa and should more than 0.05MPa.
 
Y44H bellows pressure relief valve use principle and structure description
 
1. Valve before the import medium pressure from the valve flap and the valve body seal open into the body cavity to the media pressure filled with bellows combination box, bellows and spring due to the pressure of the media pressure compression, the valve with the stem Displacement, the valve flap to the valve body seal closed, the valve before the media cut off, not for the valve after the media pressure to add. When the valve pressure after the valve down, the bellows by the adjustment of the spring diameter of the force, so that the bellows deformation, the valve stem to open the valve. So that the media through the valve body seal valve after the reduction of pressure.

2. The valve is composed of valve body, bonnet, valve, valve body, stem, bellows, spring adjustment and other components, body cavity imported assembly valve, valve ring and auxiliary spring, auxiliary spring is Keep the valve flap and the valve body seal automatically sealed, the export body cavity assembly elastic sealing element (bellows) that is to ensure that the valve after the media pressure leakage and to overcome the pressure unevenness compensation. The screw is to adjust the spring load pressure relief valve to work performance.
